Dear community,
I want to create a function, which adds automatically a crescendo from ppp
to pp to two tied pitches with different durations.
What I dont understand:
I can create a function with the same pitch and different durations, I can
also create a function with diferent pitches and same durations, but if
both are choosen freely, I can't do it. Can someon give me a hint, whats
wrong with the code?
\version "2.18.2"
\layout { \context { \Voice \override Hairpin.minimum-length = #10 } }
%different durations, different pitches, this doesn't work, why?
fadeIn = #(define-music-function (parser location PITCH durA durB)
(ly:pitch? ly:duration? ly:duration?)
#{
$PITCH $durA \<\ppp ~ $PITCH $durB \pp
#})
\new Staff { \fadeIn c' 4 2. }
%different durations, same pitch, works fine
playC = #(define-music-function (parser location durA durB) (ly:duration?
ly:duration?)
#{
c' $durA \<\ppp ~ c' $durB \pp
#})
\new Staff { \playC 2 2 \playC 4 2. }
%different pitches, same durations, works also fine
playsameRhDiffPitch = #(define-music-function (parser location PITCH )
(ly:pitch?)
#{
$PITCH 4 \<\ppp ~ $PITCH 2. \pp #} )
\new Staff { \playsameRhDiffPitch c' \playsameRhDiffPitch g' }
